IMPROVEMENT IN WATER-METERS.

Specification forming part of Letters Patent N 0. 169,368, dated November 2, 1875; application filed September 1, 1875. i

To all whom it may concern:

Be it known that I, WILLIAM B. MOUNTE- NEY, of Chicago, Illinois, have invented certaiu new and useful Improvements in Water- Meters, of which the following is a full, clear,

and exact description, reference being had to the accompanying drawings making a part of this specification, in which- Figure 1 represents a perspective View, partly in section; Fig. 2 a plan view, with the upper plate and indicator mechanism re moved; Fig. 3, a longitudinal, and Fig. 4 a vertical, section of a water-meter constructed according to my invention. Figs. 5 and 6 rep resent detail views of the valve separately.

My invention relates to improvements in water-meters, the nature of which will be hereinafter'fully explained; and it consists in the combination and arrangement of parts hereinafter described and claimed.

In the said drawings, A A represent the main casing, which is, by preference, formed circular, and divided into five chambers, B B, G G, and D, by means of partitions E F G H. Upon theupper side of the meter is arranged an index-case, I, containing a trainof gears, t, and provided with index-hands i and dial t', as shown in Figs. 1 and 4. K is the inletpipe through which the Water is supplied to the meter. The waterv entering the meter passes from the pipe K into the chamber D, in the center of which is formed a well, L, at the bottom of which is affixeda circular valveseat, L provided with four apertures, Z Z? l 1 which are opened and closed alternately by means of a circular valve, M, which is formed with a passage, m, vertically through the same slightly larger in area than one of the passages l Z Z Z and also with a passage, m,

so formed as to at all times connect one or a pair of passages, l l 1 1 with a central aperture, i in the valve-seat L The aperture 1 leads directly into the chamber 0, and the aperture P, by means of a pipe or tube, L (shown by dotted lines in Figs. 3 and 4,) passing down within the chamber 0, and through to the opposite face of the partition F, is connected with the chamber B, whilst the aperture Z, by means of the passage L is connected with. the chamber 0, and the aperture 1 by the passage L with the chamber B.

The partitions E and G areformed with circular apertures, to the edges of which are connected flexible diaphragms N I to the centers of each of which are attached plates n, provided with brackets or bearings 12/ for one end of' a vibrating ,arm, a, the opposite end of which is rigidly connected to a vertical shaft, a turning at its lower end in the bearing a, while its upper end passes up through a stuffing-box, It, into the chamber D, where the vertical shafts n are provided with lever-arms O O, which, by means of links 0 0, are connected to a crank-arm, P, connected to a vertical shaft, 19, working in a bearing, 10 and actuating the rotary valve M. On the crankarm P is formed a stud or pin, p passing through a slot in an arm, Q, Fig. 4., extending from a vertical index-shaft, q, working in bearings q, and at its upper end attached to one of the train of gears, t. The operation of the apparatus is as follows: Supposing the parts to be in the position shown by the drawings at Figs. 1, 2, and 3, and water entering the meter under pressure by the inlet-pipe K, it will first enter the chamber D, from which it will pass by the apertures l 1 into the compartmentsB O, and out of the chambers B 0, by means of the apertures l l and the passage m in the 'valve M, to the central aperture Z from which'it is conducted by a passage, R, to the outlet-pipe R, which is connected to thesupply-pipe. The water will continue to flow into the chambers B 0 until, by its pressure on the diaphragm, it has caused the arms a, by means of the vertical rods, leverarm, links 0 0, and the crank-shaft, to cause the valve M to revolve on its axis in the direction of the arrow 1, Fig. 2, when it will first close the aperture 1 and then the aperture 1 from connection with the water-supply, and at the same time first closing the aperture i and then the aperture P, from connection with the outlet-pipe R. -It will thus bereadily seen that the water under pressure is alternately conducted to, and allowed to flow from, opposite sides of the pair of diaphragms N N in such manner that both diaphragms shall be caused to traverse alternately backward and forward, and by means of the arms 11?, rods 01?, links 0 0, crank-arm P, causing the revolution of the valve M and the index-gears '5. The valve M, at each revolution, causing the chambers, to be alternately filled and emptied, a given quantity of water will he passed through the meter at each revolution, which quantity, by means of the index gears and hands, will be indicated on the dial.

S S are screw plugs or valves for withdrawing the liquid from the chambers when desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a meter for measuring liquids, the combination, with the chambers B B U G 1 and diaphragms N'N, of the chamber D, pro-' vided with a well, L, and valve-seat L having apertures Z Z Z Z controlled by a revolving valve, M, formed with passages m m, substantially as shown and described.
